The Timorese and the Malaysian Malay people objected as well (as does a significant chunk of the population of Aceh). Indonesia appears not to have allowed trivial objections of that sort to dissuade them. Indeed, after thirty years of occupation, protests and guerrilla warfare. British crown colonies for 60% of the twentieth century. Historic claims to sparsely populated territory. Obviously any "Goa" would have to be pulled before the UN recognised the former territory as a nation. Botswana, Lesotho and Swaziland remained British protectorates up until 1966. I have been talking historically across the twentieth century, not just now in 2019. There is an underlying assumption there that race and ethnicity trump all other considerations. Now that is often true, but the German Swiss for instance have never (not since the 1840s at all events) wanted to be part of Germany or Austria and Malaysia has shown no desire to be assimilated with Indonesia. Nor have unification attempts in the Arab nations ever worked very well. Many Chinese in Macau and Hong Kong were extremely relieved not to be part of Mao's PRC because they had a degree of liberty of conscience, religion and economic activity that they would not have enjoyed in the unoccupied Chinese territories.
